Antecedents and Consequences of Job Stressors: A Study in a Third World Setting

The present study investigates the antecedents and consequences of job stressors, especially role conflict and role ambiguity, in an environment where multiculturalism is a dominant feature of the workforce. This study used a sample of 397 employees in various manufacturing and service organizations in the United Arab Emirates (UAE). Path analysis revealed that age is negatively related to role conflict and positively to role ambiguity, and that nationality is positively related to role ambiguity. Results further indicate that role conflict directly and negatively influences job satisfaction, whereas role ambiguity directly and indirectly influences job satisfaction. Role conflict (directly), role ambiguity (directly and indirectly) and positively influence absenteeism. Both role conflict and role ambiguity negatively influence affective and behavioral tendency dimensions of attitudes toward organizational change, while role ambiguity directly and negatively influences cognitive attitude toward organizational change. Implications, limitations, lines of future research, and contributions were discussed.

The analysis of experience: John Dewey and Elsie Ripley Clapp on desire and thinking, 1911

Unpublished correspondence with Elsie Ripley Clapp, along with extensive notes for a 1911 course, The Analysis of Experience, provide the context for a consideration of John Dewey's discussion of the relation between desire and thinking. Dewey's philosophic point of view is portrayed as it was developing in his own mind. The unity of thought and desire, the necessity of making objects of inquiry, the identification of thinking and acting, are themes in these materials which would appear in their published form in such works as Essays in Experimental Logic, Democracy and Education, and Human Nature and Conduct. In the unpublished materials, Dewey is seen as a naturalist at work in his laboratory, reworking his ideas and acknowledging Clapp's assistance in getting Dewey to connect practical situations in life with the philosophic distinctions under development. The 1911 materials are an excellent connection between problematics in Dewey's earlier writings on ethics, epistemology, and logic, and his later writings, on the same subjects in the 1920's and 1930's.     

Enumeration and simulation methods for 0–1 matrices with given marginals

Data in the form of zero-one matrices where conditioning on the marginals is relevant arise in diverse fields such as social networks and ecology; directed graphs constitute an important special case. An algorithm is given for the complete enumeration of the family of all zero-one matrices with given marginals and with a prespecified set of cells with structural zero entries. Complete enumeration is computationally feasible only for relatively small matrices. Therefore, a more useable Monte Carlo simulation method for the uniform distribution over this family is given, based on unequal probability sampling and ratio estimation. This method is applied to testing reciprocity of choices in social networks.The author wishes to thank Cajo ter Braak and John Birks for pointing out the relevance of this subject for ecology; and also Albert Verbeek and Ivo Molenaar, a referee, the Editor, and the Associate Editor for their comments. An earlier version of this paper was presented at the Stockholm Conference on Random Graphs and Applications (April 25–27, 1989), organized with financial support from the Swedish Council of Research in the Humanities and the Social Sciences.     

Ordinal state-trait regression for intensive longitudinal data

In many psychological studies, in particular those conducted by experience sampling, mental states are measured repeatedly for each participant. Such a design allows for regression models that separate between- from within-person, or trait-like from state-like, components of association between two variables. But these models are typically designed for continuous variables, whereas mental state variables are most often measured on an ordinal scale. In this paper we develop a model for disaggregating between- from within-person effects of one ordinal variable on another. As in standard ordinal regression, our model posits a continuous latent response whose value determines the observed response. We allow the latent response to depend nonlinearly on the trait and state variables, but impose a novel penalty that shrinks the fit towards a linear model on the latent scale. A simulation study shows that this penalization approach is effective at finding a middle ground between an overly restrictive linear model and an overfitted nonlinear model. The proposed method is illustrated with an application to data from the experience sampling study of Baumeister et al. (2020, Personality and Social Psychology Bulletin, 46, 1631).     

Self-compassion at work: A self-regulation perspective on its beneficial effects for work performance and wellbeing

The work environment is fraught with complex demands, hardships, and challenges, highlighting the need to approach work with self-compassion each day. We propose that work self-compassion—a mindset of kindness, gentleness, and care toward oneself as an employee—may generate the resources and motivation needed for self-regulation at work. Drawing from integrated self-control theory (ISCT) and theory on self-compassion, we suggest that on days when employees hold a work self-compassionate mindset, they will exhibit greater work performance and wellbeing via enhanced resource capacity and motivation. In an experimental experience sampling study, we found that a work self-compassionate mindset reduced depletion and increased work self-esteem and thereby heightened daily work engagement and daily resilience. Consequently, employees made greater goal progress at work and experienced higher meaning in life. In a supplemental study, we show that state self-compassion at work is associated with unique variance in work outcomes beyond compassion received from coworkers. We discuss theoretical and practical implications for self-compassion in organizational contexts.     

A systematic review suggests marked differences in the prevalence of infant-directed vocalization across groups of populations

Anthropological reports have long suggested that speaking to young children is very infrequent in certain populations (notably farming ones), which is in line with scattered quantitative studies. A systematic review was undertaken to use available literature in order to estimate the extent of population variation. Database searches, expert lists, and citation searches led to the discovery of 29 reports on the frequency of vocalizations directed to infants aged 24 months or younger, based on systematic observations of spontaneous activity in the infant's natural environment lasting at least 30 min in length. Together, these studies provide evidence on 1314 infants growing up in a range of communities (urban, foraging, farming). For populations located outside of North America, the frequency with which vocalization was directed to urban infants was much higher than that for rural infants (including both foraging and farming, medians = 12.6 vs. 3.6% of observations contained infant-directed vocalization behaviors). We benchmarked this effect against socio-economic status (SES) variation in the United States, which was much smaller. Infants in high SES American homes were spoken to only slightly more frequently than those in low SES homes (medians = 16.4 vs. 15.1% of observations contained infant-directed vocalization behaviors). Although published research represents a biased sample of the world's populations, these results invite further cross-population research to understand the causes and effects of such considerable population group differences.     

虚拟路径整合的学习效应

路径整合指通过自身运动信息对自身位置进行更新的过程。本研究使用头盔式虚拟现实系统和分段式迷宫, 在两个实验中检验在同样布局的外出路径上重复地进行路径完成任务是否会改善被试的反应表现。实验1中的外出路径具有相对较简单的空间布局, 实验结果表明, 男性和女性被试均在反应时、位置误差、角度误差上表现出了学习效应, 即第二次在同样空间布局的外出路径上进行路径完成任务时的表现比第一次有了显著的改善。实验2中的外出路径具有更复杂多样化的空间布局, 而实验结果表明, 男性和女性被试均在反应时和比例位置误差上表现出了学习效应, 但是路径更复杂时要求更多次数的重复才可以提高路径整合成绩。这些研究结果为路径整合能力训练的可行性提供了初步的实证依据。     

统计概要表征的内容与机制

人类能够快速提取集合刺激中的统计信息, 并形成以集中趋势和变异性为主要内容的统计概要表征。根据注意资源的使用, 统计概要表征的加工方式可分为分布式注意下的整体加工和聚焦注意下的个体加工。两种加工在工作记忆中相互影响, 共同构建了对集合刺激的表征。统计概要表征适用于多种刺激类型, 发生在低水平和高水平加工中, 因而可能是一种普遍的知觉加工方式。未来研究可关注统计概要表征的神经基础及其对决策的影响。
